To nl] wlw/n t 'may concern.'

lie it known that I, vimini 1. Eaux- 1n-;.\1:'r. a citizen of the UnitedStates, and. a resident of Indianapolis. in the'couutv ot' Marion andState oi indiana, .have invent` edanew and useful Improvement in SignalDevices tor Yehicles; aud I do hereby declare the following to b'e afull, clear, and exact dcscrlptxou thereof.

M v invention relates to a signaling device for vehicles, .and hasspecial reference to mize, upon the time ot' the driver ot a vehicleandwill assist traliic corner-men on the streets inavoiding congestion. oftraflic through the driver of the vehicle indicating to such persons,vehiclesY and others at some distance from him the direction he intendsto take at the next intersecting street or crossing.

To these ends my invention consists, generally stated, in the novelarrangement, construction and combination of parts, as

hereinafter more specifically set forth and described and particularlypointed out in the claims. y

To enable, others skilled in the art to which my invention appertains toconstruct and use my improved signaling device for vehicles, I willdescribe the same more fully, referring to the accompanying drawings, in

Figs. 4 and 5 are front and topviews respectively of the device detached from the automobile. Fig. 4Gis a side View ot the operating-lever. Fig. 7 isv a side View of thedetached signaling device.

Like symbols of referenceY herein indicate like parts in each ofthefigures of the drawing.

As illustrated in the drawing my ini form ofan automobile A. andconsists mainly of a controlling end B and a signaling end B, each ofwhich is provided with'V a fluid operated cylinder l and 3 refspectively, and connected together and at each cud of each ot saidcylinders by a line of tubes or pipes 2, which are connected to threadedopenings (Z and L in the cylinder headsa and I respectively and carrythe op- .erating fluid. Each ot the cylinders l and 3 has a pistontherein composed of the two piston'heads 3", which are connected by apiston rod, and each of which has a rack O and f7 respectively, upon thetop sui-tace ot the same for engaging quadrant pinions N and f,respectively, while said heads have disks' 71,' and i provided withtongue and groove members m and t which form-,on the periphery of saiddisks a stuffing box fn.. rIhe racks O and q each rest upon supports Wando respectively. which are each placed immediatelybelow the center ofits quadrant pinion N and frespectively, and' in such manner as toprevent the, rack springing away from its pinion in operation.

Anieuwe 4ment the liquid in sucht pipes is moved accordingly. By suchmovement of the liquid in the pipes 2, thepiston in the cylinder 3 willrespond therewith, and thus operate.

the movable signaling arm composed of the portions or pieces 4 and 5,through the medium of the quadrant f engaging with the rack q in saidcylinder 3 and such quadrant being adapted to operate the chain c andwheel a.4 lVith the operating lever 6 pushed forward the movablesignaling arm rests in a position of complete extension with bothportions or pieces 4 and 5 of the same in a horizontal plane or line, asShown in ig.l 7, while partly reversing said lever 'will reverse saidarm so that said portions, or pieces will assume a vertical po- -sitionas shown in Fig. 7A, and with such lever pushed or pulled completelyback such arm by such portions or pieces would rest in a position ofcomplete extension opposite to that shawn in Fig. 7C. It is evident alsothat the portions 4 and 5 composing the movable signaling arm can bemoved by" the lever 6 to other positions between its vertical andhorizontal positions, such as is shown inFig. 7 B. Itwill thus be seenthat the signal device can be controlled by the driver from his seat inthe vehicle, and the signal can be set by the driver, independent of theoperation of the vehicle, so as to point to the right, left or verticalposition. lt will thus allow the driver approaching a corner where hewishes to turn tol the right or lett to set his signal accordingly atsome distance from the corner, in which position it will remain with nofurther attention until he desires to again change his course of travel,and when such signal is set in a vertical position it will indicate thatthe driver is going straight ahead. It will also be seen that with thesigna-l so set the driver has the free use of both hands and feet forother purposes and when he blows his horn or rings hi s. bell, as is nowrequired,

persons hearing his alarm canl recognize at once upon Seeing his signalthe direction he intends going, and thereby govern themselvesaccordingly, wlithout the` danger of being run into by the vehicleunexpectedly using the same crossing they intend to' use,

- or being uselessly ldelayed in their movements by not readily knowingthe direction the driver intends taking.

It will further be obvious that the traffic.

cornerman-hearing the alarm of. the horn or bell on the vehiclecantellat a glance the direction the'driver desires to go and at once get himinto line with the moving traiiic,

l which will thus avoid many useless delays of the vehicle and enablesuch corner man to more readily regulate traihc and avoid congestion, asSuch signal device isalwaysnndicatingr the direction the driver desiresto go, such as in pointing to the right, or to the left, or in avertical position to indicate going straight ahead, while for nights1g-,

naling the lamp at the outer end of the signaling arm can be suitablycolored so as to be readily distinguished :from the fixed lamps.

My improved signaling device can'be applied. to automobiles, trucks andvarious other kinds of vehicles, and various modifications and changesin the construction, design, application and operation of the device maybe, resorted to without departing from the spirit of the invention orsacrificing any of its advantages.
